Abstract

PURPOSE:To permit switching of a plurality of crops processing devices from the stopped condition into the driven condition thereof without providing an engine with a heavy load by a method wherein a plurality of clutches are operated to be engaged sequentially at proper time intervals. CONSTITUTION:Timers 25a-25d, setting the time from the operation of a switch 23 to the condition of respective clutches 21a-21d, are provided between the switch 23 and the solenoid clutches 21a-21d so that the clutches are operated to be engaged at a proper time intervals in the sequence of the fourth clutch 21d, the third clutch 21c, the second clutch 21b and the first clutch 21a. When the machine is under the condition of crops processing running, a straw carrying device 8, a field chain 2, a straw discharging chain 11 and a discharged straw cutter 12 are driven automatically, while the above-described devices 8, 2, 11, 12 are stopped automatically when the machine is not under the condition of the crops processing running.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transmission clutch operating structure for a crop harvester equipped with a plurality of crop processing devices.

In the above-mentioned crop harvesting machine, when switching the plurality of crop processing devices from a stopped state to a driving state, conventionally, all of the plurality of crop processing devices are switched to the driving state at once, but in this case, when the plurality of crop processing devices are stopped There is an inconvenience that a large load is applied to the engine due to the startup load of the plurality of crop processing devices in the state. Particularly, when crops to be processed by the crop processing device V are supplied, the engine may be stopped due to overload.

This issue #:I was made in view of the above actual situation, and by adding reasonable measures, multiple crop processing equipment can be stopped without putting a large load on the engine. It is designed so that it can be switched from the state to the drive state.

Embodiments of the present invention will be described below with reference to illustrative drawings.

As shown in Figures 1 and 2, a crawler traveling device (1
), a device (3) for threshing while holding and conveying the stem culm stock base rearward with a feed chain (2) on the left side, and an operation g located on the right side supporting the threshing device (3). (Equipped with 41 etc.) At the front of the machine, there are a pair of left and right stalk introduction paths, (
A pair of left and right pulling devices (5), (5) that pull up the stem culms that are introduced into the AJ, a clipper-type cutting blade (6) that cuts the base of the pulled stem culms, and a cutting blade that cuts the stem culms while merging them. A pair of left and right stem culm raking backers +71, +71 are sent to the rear, and a stem culm transporter that transports the merged stem culms to the rear, changes the sideways posture VC at the end of the conveyance, and delivers them to the threshing device (3). A reaping processing section equipped with the device (8), etc. is installed on this machine in a state where it is supported by a cylindrical frame +91 VC, which is also used for the UJ Goose and is pivoted to be vertically swingable around the horizontal axis (X1).
The frame (8) has a hydraulic cylinder (10
1 is installed at the rear of the threshing device (3), and a disc-shaped straw cutter (11) is installed at the rear of the threshing device (3) to shred the waste straw after threshing that is conveyed by the straw removal chain (11) and discharge it into the field. is installed, and as the machine advances, the stem culms planted in the field are lifted up and harvested, the harvested stem culms are sequentially threshed, and the waste straw after threshing is shredded and released into the field. It is configured to automatically and continuously perform the cutting, and the mowing processing section can be adjusted up and down in order to adjust the cutting height and avoid contact with the ground when traveling on the road or on the headland. It is.

As shown in FIG. 8, a part of the output of the engine (1) installed at the bottom of the driver's seat (4) is transmitted to the threshing device input shaft (8a ) VC transmission, and the power of this input shaft (8a) drives the handling cylinder (15) and the threshing material sorting device. In addition, part of the output of the engine (131) is transmitted to the traveling mission booth Uη via the heald tension type main transmission U1 clutch Kasumi, and a part of the power transmitted to the traveling mission booth is transferred to the heald tension type main transmission booth Uη. Work device d River Den U] Valve the clutch +19) and work device il! It has a four-axis transmission counter for driving.
Then, a part of the rM11 force transmitted to the counter shaft a is transmitted by a bevel gear to the reaping drive transmission shaft 4 provided with a VC in the cylindrical 7-ray A (9), and the power of this transmission shaft is It is configured to drive the pulling device (5), cutting blade (6), and backer (7). In addition, part of the power transmitted to the counter shaft is transferred to an electromagnetic second transmission clutch (2
1a) to the driving bevel gear (8a) of the stem culm conveying device (8), and part of the power of the counter shaft (1) is fed through the electromagnetic second transmission clutch (21b) 'Th. Chain (2) input chain (2a)
It is transmitted to Further, a drive shaft (2) for the waste straw processing unit is provided which is interlocked with the handling cylinder u[i)K bevel gear, and a part of the power of this drive shaft (2) is transmitted to a third electromagnetic transmission clutch (21c). A part of the power of the drive shaft (2) is transmitted to the straw removal cutter (121) via the electromagnetic fourth transmission clutch (21d). The threshing clutch t141.The main transmission clutch (the main transmission clutch and the working equipment Kawaden 1 clutch H are each installed near the driver's seat (4).

It is composed.

The electromagnetic first to fourth transmission clutches (21a)...
Each of them is biased toward the cutting edge so as to be turned on by energization, and an electric switch (2) for clutch-on operation is placed at the beginning of the conveyance in the stem culm conveyance device (8), as shown in FIG. When a stem culm is present in the area, the stem culm is suppressed and retracted, and when there is no stem culm, the stem culm conveyance device is energized and oscillated to the side. It is provided in such a way that it is operated to suppress when it swings backward, and furthermore,
Between switch A and each clutch (21a), each clutch (21a) is connected to the fourth clutch (21d), the eighth clutch (21d), and so on.
Clutch (21c), 2nd clutch (211+), 1st
A timer is used to set the time from when the switch (2) is turned on until each clutch (21a) is energized so that the clutches (gia) are turned on and operated sequentially at appropriate intervals. Device (25a), (25b)

In short, as shown in Fig. 6, - When going around to move on to the next process after restoration, the discharge of waste straw into the field is stopped, and when going around, the Vc pile body or the waste straw is removed. This is to prevent people from stepping on it.

The present invention can be used after harvesting various crops, such as onion harvesters, rush harvesters, etc., in addition to combine harvesters.

In addition, when configuring the clutch operation mechanism, the engaging operation command is manually given, and the clutch operation mechanism is
The specific structure can be modified in various ways, such as using a fluid pressure sill as the mechanism.

In short, the drive clamp operating structure of the crop harvester according to the present invention includes a plurality of crop processing devices (8).

+21, (lli, (12;); a plurality of transmission clutches (fla), (21b;
